… The Angara flora is also called the Kuznetsk flora because it is well developed in the Kuznetsk coalfield. The main plant fossils found are the macrophyllous Angaridium and Angaropteridium , the ginkgophyllum and Rhipidopsis , which are similar to ginkgos, and the arthropods Rhyllotheca and Paraschizoneura . The Gondwana flora of the Southern Hemisphere, which is separated from the Angara flora by the Tethys Ocean, is made up of 90% simple-leafed Glossopteris , indicating that it arose in a harsh climate. However, the macrophyllous plants in the Angara flora do not have simple leaves, and are all pinnately compound-leafed plants. This indicates that they arose in a milder climate than the Gondwana flora, based on the principle that simple leaves arise from pinnately compound leaves due to environmental deterioration. … *Some of the terminology that mentions "Angaridium" is listed below.

… アンガラ植物群はクズネツク炭田によく発達するのでクズネツク植物群とも呼ばれる。大葉類のAngaridium,Angaropteridium,イチョウ類に近い形のGinkgophyllum,Rhipidopsis,有節類のRhyllotheca,Paraschizoneuraなどが産出する主要な植物化石である。アンガラ植物群にテチス海をへだてて対立する南半球のゴンドワナ植物群は単葉のグロッソプテリスGlossopteris類が9割も占めて,きびしい気候下に生じたことを示しているが,アンガラ植物群の中の大葉類には単葉がなく,羽状複葉性の植物ばかりで,これは単葉は羽状複葉から環境の悪化が原因して生ずるという原則からみて,ゴンドワナ植物群よりもゆるやかな気候下に生じたことを示している。… ※「Angaridium」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
